The International Monetary Fund says the Taliban, now in control of Afghanistan, will not be able to access nearly half a billion dollars in reserve funds, amid mounting pressure by the international community, including the U.S. Treasury Department.

This comes as a new allocation of assets, known as special drawing rights (SDRs), is scheduled to go out on August 23. An estimated $450 million of the $650 billion allocation was designated for Afghanistan.

"As is always the case, the IMF is guided by the views of the international community. There is currently a lack of clarity within the international community regarding recognition of a government in Afghanistan, as a consequence of which the country cannot access SDRs or other IMF resources," a spokesperson for the IMF said in a statement to CBS News.

The U.S. is the largest contributor to the IMF. A Treasury official said the department is taking steps to prevent the Taliban from accessing SDRs.
